To all whom it may concem:

Be it known that I, Alierta Cairranrmta citizen of the United States, residlng m Chicago, 'in the county of Cook and State of Illinois, have invented n new and. useful Improvement in DumpCars, of whlch the following is a speoilica.t1on.

My invention relates to improvements 1n dump cars.

My invention consists 1n the novel construction of parts and devices and 1n the novel combinations and sub-combinations of parts and devices herein shown and described and more particularly specified in the claims.

In the accompanying drawing forming a port of this specification, Figur-e1 1s a side elevation of a4 dump car embodying my 1nvention, one duplicate half of the car being omitted. Fig. 2 is a plan view of same. Fig. 3 is a vertical cross section. Fig. 4 1s :in enlarged detail elevation of the door operating mechanism. Fig. 5 1s i top. or plan view of same. Fig. 6 is a side view of saine, showing the operating shaft in cross section- Fig. 7 is a detail view of the terminal or locking link of the door operating mechanism. Fig. 8 is a detail side view of the rotary su porting pin between the terminal link anc the door supporting bar. Fig. 9 is an end view of said pin. Figs. 10, 11 and 12 are views similar to Fins. 1, 2 and 3 respectively, showin'g the application of my invention to a gondola car; and Figs. 13, 14 and 15 are views similar to 1, 2 and 3 respectively, showing the application of my invention to a hopper car 1n which the doors are hinged transversely instead of longitudinally, as in Figs. 1, 2 and 3.

In the drawing, 1 represents ay dump car, 2 the wheels thereof, 3 the center sills, 4 the upright sides of the cnr bod 5 the floor or bottom, the same bein pre erably inclined or hopper shaped at the ends, 6 the longitudinal, central hopper sheet extending over the center sills, 7 transverse hopper sheets extending across the car between the door openings 8 and 9, 8 and 9 on each side of the central hopper sheet, and 10, 11, 12 and 13 are longitudinally hinged doors closing the door openings on each side of the central hopper sheet and between the trans. verse hopper sheets, the doors 10 and 11 being hinged at their inner longitudinal edges adjacent to the center sills or central hopper sheet, and connected together by a bent bridge member 14 so that they muy be operated together or as one door; and the doors 12, 13 being hinged at their outer longitudinal edges at or near the outer side of the car, and the doors l2, 13 being connected together by a bent bridge member 14 so that they may also be operated together or as one door. The doors 10, 12, and the doors 11, 13 moet together at their free or swin 'ng edges, as will be readily understood m Figs. 2 and 3 of the drawing.

15 is the operating shaft of the door operating mechanism.l the same extending as shown in Figs. 1, 2 'nd 3, transversely across the car under the transverse hopper sheet 7 and between the adjacent ends of the doors 10, 11 and 12, 13, the same having suitable bearings 16 in the central hopper sheet and in the car sides, and preferably extendin throughv the center sills. The operating s aft is provided with two polyvonal drums 17, each preferably four sid-'ed and having an upper or locking face or side 18, furnished with a shoulder or projection 19, and located above or in line with the meeting edges of the doors 10, 12 and 11, 13. Each of .the drums 17 is further provided with a pivot lug 20 and with guides or flanges 21 on the side thereof opposite the pivot lug` 20. The locking block or termi-v nal link 22 has on its under face 23 a shoulder2=l ada ted to interlock with and engage the shoul er 19 on the upper or locking face 1B of the drum 17. The locking block or terminal link 22 is flexibly connected to the drum 17 or its pivot lug 20 by connecting links 25, preferably three in number, and fitting and corresponding to three sides of the drum 17 while the locking block or terminal link 22 fits and corresponds to the remaining side thereof. The final link 25 is connected by a pivot pin 26 to the lug 20 of the drum 17 and similar pivot pins connect the several links with each other and with the locking block or terminal link 22.

The locking block or terminal iink 22 is furnished with a central bore 27, the axis of which is directly above the axis of the operating shaft 15 when the doors are closed to receive the rotary supporting pin 28 which is cylindrical at its middle portion, and which is provided with two upright flat sided end portions 29, each furnished with an eye 30 to receive the connecting bolt"8'1','"`which passes through the 'awsl32 of the door supporting bar 88, an which jaws 82 embrace the flat sided end 29 of the rotarv supporting pin 28, thus u'ordmp; a double or two-way rotary connection between the locking block 22 of the door operating mechanism, and each of the door supporting bars 33, one of which connects with the brid member of the two connected doors. ach of the door supporting bars 33 has a double or two-way rotary connection with the bridge member 14 of the doors, this double or two-way rotary connection preferably consisting of a supplemental coupling 34 connected by a pivot 35 with the lower end of the supporting bar 33 and by a pivot 36 with the bridge member 14 of the doors. The four doors, on each side of the central hopper sheet are thus simultaneously operated by one and the same door operating mechanism. All eight doors on both sides of the central hopper sheet are also simultaneously operated from the same operating shaft 15.

In the modification illustrated in 10, 11 and 12, the construction of the Figs. door operating mechanism 1s the same as above described, these figures showing the application of the invention to a gondola car in which the dum doors 37, 38, 39 and 40 are longitudina y d and centrally arranged between the center sills, the door operat' shaft 15 extendingr transversely to one side of the car between the transoms or transverse frame members 41 of e car.

In the modification illustrated in Figs. 13, 14 and 15, the construction of the door operating mechanism is the same as that above described, these figures showing the application of my invention to a dump car in which the doors 42, 43, 44, 45 and 46, 47, 48 and 49 are h' ed or arranged transversely instead of longitudinally of the car. In this modification, the door operating shaft 15 extends longitudinally under the central hopper sheet 450, and it is provided with a bevel gear 51 at one end meshing with a bevel gear 52 on supplemental shaft 53 which extends out. to the side of the car.
